As a rotating support part that has a direct impact on vehicle safety,the safety of wheel hub is particularly important.The honeycomb structure is a lightweight,high-strength structure whose stress characteristics are highly similar to those of the wheel hub under bending conditions.Therefore,based on the honeycomb structure,the bionic design of the wheel hub was carried out,and the response surface optimization was carried out.The final simulation results show that the bending fatigue life of wheel hub reaches 1.72×105 times,which meets the requirements of the national standard GB/T 5334—2021 of commercial vehicle wheel hub bending fatigue life.
